Low-Noise Balanced Photodetectors

Unlike the previous two models, this unit focuses on high-frequency AC signal detection. It features an AC Coupled design that automatically filters out background DC light, simplifying signal processing and enabling a detection bandwidth of up to 200 MHz.

Although the gain is fixed at 30 kV/A, its compact design and single power supply (5V) make it highly suitable for integration into portable or miniaturized systems.
